loading is EXTREMELY quick now. it was already around 5 to 6 seconds when fast traveling, and around the same while entering interiors.
that now has been reduced to literally around 1-2 seconds. [censored] amazing.
. for an example, check out the IGN youtube video which references this patch. it's full of resentful Xbox 360/PS3 [censored] commenting on how Bethesda is concentrating "too much" on PC.
I've already seen a few snipes for nothing. its a great thing they're doing. and honestly if you're griping about THIS (note I griped about Marriage where they could have done more interesting things) then you haven't been around long to know the Bethesda hasn't done anything like this Since the early days of Morrowind....
Still won't update my game until I get my killcam toggles, though. 
Slaughtered lots of people, animals, and 2 dragons with my bow. The zoom and slow time perks helped a lot though. I hope they add the ability to shoot behind you while riding forward (the famous Parthian shot that many horse archers in history used) and make it impossible to shoot to your right side as right handed horse archer can't shoot to their right.
